The East African rupee was a currency used in the eastern part of Africa in the early and mid-20th century. The currency was primarily used in countries like Kenya, Tanzania, and Uganda, which were under the British colonial rule at the time. Today, the East African rupee is no longer in use, and some synonyms for the currency include the British East African rupee, East African shilling, and the Zanzibar riyal. These synonyms reflect the various historical contexts in which the currency was used and suggest the diverse cultural and economic influences that have shaped the region over time.
